COVID-19: Known & Still Unknown



Day 62: Stay Safe Minnesota

An emergency physician and Brown University associate professor of emergency medicine, Dr Megan Ranney told to CNN what we know and still don’t know about Covid-19.

An emergency physician & Brown University professor Dr. Megan Ranney has some perspective on coronavirus. The CNN reports that Dr. Megan Ranney, a Associate Professor of Emergency Medicine at the Brown University, testified about coronavirus before the US congress. In a CNN interview, Dr Ranney said the followings about coronavirus – what we know and what we still don’t know.

About Virus Genome

Genomic information helps us to (a) identify if/when it mutates, (b) track its spread (c) identify treatments and vaccines because we focus in on specific targets on the virus.

About Social Distancing

‘Social distancing’ is to prevent transmission. Social distance from almost everyone is advised because we don’t know who might be infectious. But if we know exactly who is sick, and if those people stay isolated from others, then the rest of us can go about our business without worrying.

Masks Wearing While Outdoors

Being outdoors is lower risk than being indoors, because the virus dissipates. It’s possible to get infected if you’re downwind from someone who’s sick, but it’s unlikely.

Relaxed Social Distancing

We can relax social distancing with close families/friend groups can gather if we know they are not sick. BUT it’s also important to have random testing of asymptomatic people — because people can be infectious before they have symptoms, and current data suggests that 1/3 of people don’t ever get symptoms.

High-risk exposure = inside, close together. The longer you’re close to someone who’s sick, the higher the chances of your getting infected. We can’t yet say “2 feet” or “6 feet” or “12 feet” is adequate inside — current recommendations are 6 feet but there’s debate about that.

High Risks Exposure

There are careless peoples in our society. A consistent high quality public health messaging is important. We need to make it easy for people to stay home if they’re sick, create NORMS that they will stay home, and enforce isolation by checking on people daily, and maybe even having fines if they break isolation. This is more extreme but is sometimes needed.
